International Bird Strike Committee
Aircraft repeatedly prove that birds and aircraft cannot occupy the same airspace at the same time. In an average year about 3000 birdstrikes cause 50-80 million US dollars in damage to USAF aircraft. To the worldwide aviation fleet this problem is estimated to cost more than three billion US dollars per year. Factors for consideration in establishing birdstrike resistance requirements, and in ...
متن کاملThe Costs of Bird Strikes and Bird Strike Prevention
Collisions between birds (and other wildlife) and aircraft are known to cause substantial losses to the aviation industry in terms of damage and delays every year. Techniques exist to control bird numbers on airfields and hence to reduce the number of wildlife strikes, but they are applied at widely different levels from airport to airport. Some of this variation may be due to differing levels ...
متن کاملMaterial tailoring and moduli homogenization for finite twisting deformations of functionally graded Mooney-Rivlin hollow cylinders
We analytically analyze finite plane strain twisting deformations of a hollow cylinder made of an isotropic and inhomogeneousMooney-Rivlinmaterial withmaterial moduli varying in the radial direction. The cylinder is deformed by applying either tangential tractions on the inner surface and tangential displacements on the outer surface or vice versa. The radial variation of the moduli is found th...
متن کاملA Protocol for Bird Strike Risk Assessment at Airports
In order for airports to manage the bird strike risk effectively, a risk assessment process needs to be carried out to identify the major hazards at the airport, the levels of risk that they produce, and the most cost effective means of reducing that risk. Despite the fact that bird controllers, managers and consultants make informal bird strike risk assessments throughout their working lives, ...
متن کاملPrevalence of Avian Influenza in Live Bird Markets, Bird Gardens, and Zoos in Iran in 2015: A Cross-sectional Study
Avian Influenza (AI) H9N2 is endemic in Iran; therefore, it is necessary to estimate the disease prevalence among birds in live bird markets (LBMs) and assess the risk spread across the country. Accordingly, this study aimed to estimate the prevalence of AI subtypes in LBMs, bird gardens, and zoos during October and November 2015 in Iran and investigate the associated risk factors. Data related...
